I have the Carnetix P1900 2.2 with MacPac. Connected Y cable and when I turn my ignition switch on the Mac Mini will not turn on, unless I hit the power button. Right now I am just running tests in my house for setup reasons but this seems to be the first problem I have run into. I am using a ATX power supply to power the carnetix and just put a toggle switch between the ignition line which is just a 12V.
Any help would be great full.
